linux hard disk drive mini-howto

On Linux Systems each hard disk will be availabe as a seperate device file - usally located in /dev/.

IDE devices are represented by a prefix of hd:

	linux device
Primary IDE Master	/dev/hda
Primary IDE Slave	/dev/hdb
Secondary IDE Master	/dev/hdc
Secondary IDE Slave	/dev/hdd

SCSI devices on the other hand are represented by a prefix of sd:

	linux device
SCSI Device with ID 0	/dev/sda
SCSI Device with ID 1	/dev/sdb
SCSI Device with ID 2	/dev/sdc
SCSI Device with ID 3	/dev/sdd

Access to entire hard disks

The devices shown above give access to entire hard disks no regard to partitions!

For example, if you want to change/create partitions on your master drive on the secondary channel you may use cfdisk in that way:

cfdisk /dev/hdc

Correspondig for the fourth scsi device (ID 3) you have use cfdisk like this:

cfdisk /dev/sdd

Access to partitions on hard disks

Partitions are numbered from 1 to x. Detailed Information is available The Linux System Administrator's Guide (by Lars Wirzenius, Joanna Oja, Stephen Stafford, Alex Weeks)
